# MongoDb Migration Guide
|
|
|
|
## Upgrading to 1.0.0
|
|
|
|
This version introduces a general availability version of the MongoDB V2 source connector, which leverages
|
|
[Change Data Capture (CDC)](/understanding-airbyte/cdc) to improve the performance and
|
|
reliability of syncs. This version provides better error handling, incremental delivery of data and improved
|
|
reliability of large syncs via frequent checkpointing.
|
|
|
|
MongoDB now supports incremental syncs. Alternatively you can also choose to use full refresh if your DB has lots of updates but in relatively
|
|
small volume.
|
|
|
|
**THIS VERSION INCLUDES BREAKING CHANGES FROM PREVIOUS VERSIONS OF THE CONNECTOR!**
|
|
|
|
The changes will require you to reconfigure your existing MongoDB V2 configured source connectors. To review the
|
|
breaking changes and to learn how to upgrade the connector, refer to the [MongoDB V2 source connector documentation](/integrations/sources/mongodb-v2#upgrade-from-previous-version).
|
|
Additionally, you can manually update existing connections prior to the next scheduled sync to perform the upgrade or
|
|
re-create the source using the new configuration.
|
|
|
|
Worthy of specific mention, this version includes:
|
|
|
|
- Support for MongoDB replica sets only
|
|
- Use of Change Data Capture for incremental delivery of changes
|
|
- Frequent checkpointing of synced data
|
|
- Sampling of fields for schema discovery
|
|
- Required SSL/TLS connections
|
